The key to choosing the right headphone amp is not as simple as pure wattage, it’s about matching your amp choice to your specific headphone’s power requirements. Generally speaking, and depending on how loud you listen, our headphones sound wonderful from a standard smartphone or laptop listening at healthy levels. However, for an elevated experience and more loudness, a dedicated amp that is capable of delivering at least 1 watt is ideal.

B-Stock units may have some minor physical imperfections, the plus side is B-Stock units sell for a reduced price. All RAD-0’s regardless of price or condition have the same transducers, undergo the same level of testing and strict quality control, and have the same warranty. Components that have major defects will never make it into a pair of headphones. While we are not able to say exactly what imperfections are on a specific B-Stock unit, the most common imperfection that qualifies a unit as B-Stock are small imperfections within the ring. These units might additionally have nicked leather components and/or damaged metal components. These blemishes are overall quite minor and will become rarer in the future, but we’re perfectionists. We figure, rather than throwing away almost perfectly good parts, we pass the savings on to you.

It’s possible, but please double check to make sure that your cable(s) match our stock or alternate pinouts illustrated below.
